, J. HEAPS LIFTER MOTION FOR CAP SPINNING FRAMES Filed April 1, 1922'"'INVEN i O I QQf' ATTORNEY;

therewith only when engaged by the shoulder 55, and the chain 57 is aconnecting member which at all times extends between the monkey O andsaid member 56 and which moves therewith when member 56 revolves.

The difference between the new construction, and the old construction isthat in the old construction a gear engages and disengages a rack, whilein the new construc tion the members which perform the same functionsare in continual engagement thereby preventing wear and banging.

As shown in Fig. 5, I may use in connection with a rack L, a gear suchas 8%, which is always in engagement therewith and which has teeth 85which are engaged at the appropriate time by teeth 86 on shoulder 87 ofscrew F when it is screwed up.

Gear 84 is not threaded but is loose on the threads 20, and thereturning spring 88 between 8% and 22 and stop 89 fixed to rail B keepgear 84: and rack L always in engagement. They limit the movement of theparts and return them to their normal positions. V

In this construction, the rack is the connecting member which alwaysextends between monkey O and the revoluble member 84 loose on thethreads of the motion screw and normally revoluble thereon'but revolubletherewith when engaged by teeth 86 on shoulder 87.

I claim:

1. In a Scaife builder motion for spinning frames; the combination witha motion screw having a shoulder beyond which its threads extend; of along lever; a motion nut through which the motion screw threads pass,carried by the free end of said long lever; a monkey slidable on saidlong lever; a revoluble member loose on the threads of said motion screwand revoluble therewith, only when engaged by the shoulder; and aconnecting member which at all times extends between said monkey andsaid revoluble member and which moves the monkey when the revolublemember revolves.
